Abstract Purpose Critical Care Nephrology is an emerging sub-specialty of Critical Care. Despite increasing awareness about the serious impact of acute kidney injury (AKI) and renal replacement therapy (RRT), important knowledge gaps persist. This report represents a summary of a 1-day meeting of the AKI section of the European Society of Intensive Care Medicine (ESICM) identifying priorities for future AKI research. Methods International Members of the AKI section of the ESICM were selected and allocated to one of three subgroups: “AKI diagnosis and evaluation”, “Medical management of AKI” and “Renal Replacement Therapy for AKI.” Using a modified Delphi methodology, each group identified knowledge gaps and developed potential proposals for future collaborative research. Results The following key research projects were developed: Systematic reviews: (a) epidemiology of AKI with stratification by patient cohorts and diagnostic criteria; (b) role of higher blood pressure targets in patients with hypertension admitted to the Intensive Care Unit, and (c) specific clearance characteristics of different modalities of continuous renal replacement therapy (CRRT). Observational studies: (a) epidemiology of critically ill patients according to AKI duration, and (b) current clinical practice of CRRT. Intervention studies:( a) Comparison of different blood pressure targets in critically ill patients with hypertension, and (b) comparison of clearance of solutes with various molecular weights between different CRRT modalities. Conclusion Consensus was reached on a future research agenda for the AKI section of the ESICM.

Acute kidney injury (AKI) is a common complication in critically ill patients with an incidence of up to 50% in intensive care patients. The mortality of patients with AKI requiring dialysis in the intensive care unit is up to 50%, especially in the context of sepsis. Different approaches have been undertaken to reduce this high mortality by changing modalities and techniques of renal replacement therapy: an early versus a late start of dialysis, high versus low dialysate flows, intermittent versus continuous dialysis, anticoagulation with citrate or heparin, the use of adsorber or special filters in case of sepsis. Although in smaller studies some of these approaches seemed to have a positive impact on the reduction of mortality, in larger studies these effects could not been reproduced. This raises the question of whether there exists any impact of renal replacement therapy on mortality in critically ill patients—beyond an undeniable impact on uremia, hyperkalemia and/or hypervolemia. Indeed, this is one of the essential challenges of a nephrologist within an interdisciplinary intensive care team: according to the individual situation of a critically ill patient the main indication of dialysis has to be identified and all parameters of dialysis have to be individually chosen with respect to the patient’s situation and targeting the main dialysis indication. Such an interdisciplinary and individual approach would probably be able to reduce mortality in critically ill patients with dialysis requiring AKI.

The purpose of this study was to evaluate the efficacy and safety of danaparoid in the treatment of critically ill patients with acute renal failure and suspected heparin-induced thrombocytopenia (HIT) needing renal replacement therapy (RRT). We conducted a retrospective analysis of 13 consecutive intensive care patients with acute renal failure and suspected HIT who were treated with danaparoid for at least 3 days during RRT. In eight patients, continuous venovenous hemofiltration was performed. The mean infusion rate of danaparoid was 140 ± 86 U/hour. Filter exchange was necessary every 37.5 hours. In five patients, continuous venovenous hemodialysis was used. A bolus injection of 750 U danaparoid was followed by a mean infusion rate of 138 ± 122 U/hour. Filters were exchanged every 24 hours. In 7 of 13 patients, even a low mean infusion rate of 88 ± 35 U/hour was efficient. Mean anti-Xa (aXa) levels were approximately 0.4 ± 0.2 aXa U/mL. Persistent thrombocytopenia despite discontinuation of heparin treatment was observed in 9 of 13 patients, owing to disseminated intravascular coagulation (DIC). HIT was confirmed by an increase in platelet count and positive heparin-induced antibodies in 2 of 13 patients. No thromboembolic complications occurred, but major bleeding was observed in 6 of 13 patients, which could be explained by consumption of coagulation factors and platelets due to DIC in 5 of 6 patients. Nine of 13 patients died of multiorgan failure or sepsis, or both. In none of these patients was the fatal outcome related to danaparoid treatment. In critically ill patients with renal impairment and suspected HIT, a bralus injection of 750 U danaparoid followed by a mean infusion rate of 50 to 150 U/hour appears to be a safe and efficient treatment option when alternative anticoagutation is necessary.

Introduction: Acute kidney injury is characterized by a sudden decrease in renal function. The objective was to determine the variables that are associated with the need for continuous renal replacement therapy and its outcome in critically ill patients treated in two intensive care units. Methods. A cohort follow-up study with reviewed clinical histories of 140 patients admitted between January-2012 and July-2015, who were receiving continuous therapy, and the main outcome was survival after discharge. Clinical variables, severity scores, disease prognosis, continuous renal replacement techniques and outcomes were collected. Results. Mean age was 61.9±17.6 years, and 60.7% were men. Septic shock was the main cause of acute kidney injury. In total, 79.4% of cases died in the intensive care units. The median dose of continuous renal replacement therapy was 28 ml/kg/hour (interquartile range: 35-37). The late initiation of the therapy between 25-72 hours after the diagnosis increased the probability that the patient would experience a fatal outcome (OR:6.9, 95%CI:1.5-33.0). Conclusions: Acute kidney injury secondary to sepsis is a frequent condition in critically ill patients and is associated with high mortality rates. In these cases, continuous renal replacement therapy was the main recourse for its treatment.

ABSTRACT The pharmacokinetics of intravenously administered levofloxacin and ciprofloxacin were studied in intensive care unit patients during continuous venovenous hemofiltration (CVVH; four patients received levofloxacin, and five received ciprofloxacin) or hemodiafiltration (CVVHDF; six patients received levofloxacin, and five received ciprofloxacin). Levofloxacin clearance was substantially increased during both CVVH and CVVHDF, while ciprofloxacin clearance was affected less. The results of this study suggest that doses of levofloxacin of 250 mg/day and ciprofloxacin of 400 mg/day are sufficient to maintain effective drug concentrations in the plasma of patients undergoing CVVH or CVVHDF.

van Bommel EFH, Leunissen KML, Weimar W. Continuous renal replacement therapy for critically ill patients: an update. J Intensive Care Med 1994; 9: 265–280. Despite continuous progress in intensive care during the last decades, the outcome of critically ill patients in whom acute renal failure (ARF) develops is still poor. This outcome may be explained partially by the frequent occurrence of ARF as part of multiple organ systems failure (MOSF). In this complex and unstable patient population, the provision of adequate renal support with either intermittent hemodialysis or peritoneal dialysis may pose major problems. Continuous renal replacement therapy (CRRT) is now increasingly accepted as the preferred treatment modality in the management of ARF in these patients. The technique offers adequate control of biochemistry and fluid balance in hemodynamically unstable patients, thereby enabling aggressive nutritional and inotropic support without the risk of exacerbating azotemia or fluid overload. In addition, experimental and clinical data suggest that CRRT may have a beneficial influence on hemodynamics and gas exchange in patients with septic shock and (nonrenal) MOSF, independent of an impact on fluid balance. We review both technical and clinical aspects of various continuous therapies, including their impact on serum drug levels and nutrient balance. In addition, an attempt is made to clarify the possible beneficial role of CRRT in reducing patient morbidity and mortality in the ICU.

We studied the biochemical and the clinical consequences of the application of continuous venovenous hemodiafiltration to the management of acute renal failure in critically ill patients. One hundred consecutive surgical and medical ICU patients with acute renal failure were entered into a prospective clinical study at an intensive care unit of tertiary institution. Intervention included assessment of illness severity by APACHE II score on admission and by organ failure score prior to initiation of renal replacement therapy; treatment of patients with continuous venovenous hemodiafiltration; and measurement of biochemical variables prior to and after therapy. Outcome assessment included incidence of complications, duration of oliguria, duration of intensive care and hospital stays, and survival to hospital discharge. Measurements and main results included the following: mean patient age was 60.9 years (range 21–81 yr); mean APACHE II score, 28.6 (95% confidence interval; 27.4-29.8); and number of failing organs, mean, 4.1 (95% confidence interval; 3.8-4.4). At commencement of continuous venovenous hemofiltration with dialysis, 79% of patients were receiving inotropic drugs and 72% were septic, and, in 35%, bacteremia or fungemia was demonstrated. Renal replacement therapy was applied for a mean duration of 186.2 hours (95% confidence interval; 149.2-223.7), with a mean hourly net ultrafiltrate production of 621 mL (95% confidence interval; 594–648) and a mean urea clearance of 28.1 mL/min (95% confidence interval; 26.7-29.5). Azotemia was controlled in all patients (plasma urea < 30 mmol/L). During the more than 18,000 hours of treatment, there was no therapy-associated hemodynamic instability. Complications were rare. They included two cases of hemofilter rupture with minor blood loss and a single case of bleeding at the site of the vascular-access catheter. Forty-three patients survived to ICU discharge, and 40 survived to hospital discharge. Continuous venovenous hemodiafiltration is a safe and an effective form of renal replacement therapy in critically ill patients. In such patients, who have a high predicted mortality rate, it was associated with a 40% survival rate. These findings suggests that continuous venovenous hemodiafiltration may be ideally suited to patients with multisystem organ failure with acute renal failure.
